With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.3336-43-4,1-Chloroisoquinolin-4-ol,as a common compound, the synthetic route is as follows.

To a solution of l-chloro-4-hydroxyisoquinoline (1.Og, 5.6 mmol) in DMF (16mL), was added 6-chloronicotmonitrile (0.55g, 4.0mmol) and K2CO3 (1.65g, 11.9mmol). The reaction mixture was heated at 7O0C for 6.5h. Solvent was removed in vacuo and residue partitioned between EtOAc (10OmL), THF (10OmL) and water (6OmL). The organic phase was washed with water (2x60mL), IM NaOH (2x40mL), brine (4OmL) and dried (MgSO4). Solvent was removed in vacuo to give the title compound: RT = 3.66min; m/z (ES+) = 282.0 [M + H]+.

3336-43-4 1-Chloroisoquinolin-4-ol 4281882, aisoquinoline compound, is more and more widely used in various.

Example 34:3-Amino-l-(3-bromo-4,5-dimethoxy-phenyl)-9-chloro-lH-4-oxa-10-aza-phenanthrene-2- carbonitrile (34)(34)l-Chloro-4-hydroxyisoquinone (790 mg, 4.4 mmol), 5-bromo-3,4-dimethoxy-benzaldehyde ( 1.077 mg, 4.4 mmol) and malononitrile (295 mg, 4.4 mmol) were taken in 40 ml ethanol at room temperature, charged with DABCO (48.4 mu, 1.46 mmol) and then stirred at 80 C under LC-MS control for 24 h. The reaction mixture was cooled down to room temperature, diluted with water to about 100 ml and the precipitates were collected by filtration, washed well with 50 % aqueous ethanol and dried under vacuum to yield the title compound (1.7 g, 3.6 mmol, 82 %).
